# Submarine Effect in Traffic Accidents
The submarine effect occurs when the occupant's body slides downward beneath the seat belt during a frontal collision. This happens especially if the seat belt is not properly adjusted or positioned correctly over the pelvis. This movement can cause serious injuries to the abdomen and internal organs, which is why it is essential to wear the seat belt correctly fastened and adjusted.
